In response to the information request issued by Noosa Council on 9 February 2016, we
provide the following information:
Water Reuse
         The Noosa Plan Water Sensitive Design Code O3 seeks water re-use in
         developments.

Item 12:      Demonstrate how captured water is utilised for all non-potable uses on site.

Response: Rainwater Re-use has been provided for external irrigation and uses in
          accordance with S3.1 of the Noosa Plan Water Sensitive Design Code. Refer to
          the attached Site Based Stormwater Management Plan (revision 3) prepared by
          Morgan Consulting Engineers for details.

Water Quality
              The Noosa Plan Water Sensitive Design Code O6 requires that run-off that leaves
              the site is treated so as not to adversely impact on the ecology and hydrology of
              downstream environmental flows.

              O9 seeks use of natural treatment strategies, including grass swales and bio-
              retention systems, vegetated filtration strips and gross pollutant traps.

              In addition, the State Planning Regulatory Policy for Water Quality details water
              pollutant reduction targets that must be achieved.

Item 13:      Provide comment to demonstrate that the applicants preferred water quality
              treatment option both achieves the State Planning Policy pollutant reduction
              targets, has the best water quality improvement efficiencies in terms of Lake
              Doonella’s water quality objectives and current stressors and meets Specific
              Outcome O9 of the Noosa Plan Water Sensitive design code to provide natural
              treatment strategies.
Response: The attached Site Based Stormwater Management Plan (revision 3) prepared by
          Morgan Consulting Engineers demonstrates compliance with the State Planning
          Policy pollutant reduction targets. Compliance with the Lake Doonella water
          quality objectives is achieved for Total Suspended Solids and Total Nitrogen
          however, the water quality objective for Total Phosphorus cannot be achieved. A
